Alyssa was surprised by her co-workers offer. The stable-hand had applied for this job due to her love of horses, but she knew she didn't love horses in THAT way, but seeing the powerful body of a stallion attached to the body of a sexy woman stirred something within her. The stable-hand found herself nodding to her co-workers question. Kayla clopped up to Alyssa and helped her remove her clothes, leaving both woman awkwardly standing in the stables butt naked.
"So, how are we supposed to do this?" Kayla asked, her foot long slab of horse meat now fully erect.
"I've got an idea, lay down on your back" Alyssa replied.
The centaur did as she was asked and, with a little difficulty, laid down on the floor. Alyssa approached her soon-to-be lover, taking in the enormity of the horsecock in front of her. Before she could get cold feet she straddled Kayla's lower body and pressed the flared tip of her cock against her lower lips. The woman then steeled herself before lowering her body. A mixture of pain and pleasure coarsed through Alyssa's body, forcing a moan from her lungs. She continued to slowly spear herself on Kayla's cock, the centaur rendered speechless by the sight. Every time she got another inch into herself Alyssa came, forcing the woman to stop so her legs didn't give out beneath her.
After nearly twenty minutes Alyssa felt the tip of Kayla's cock press against her cervix, signalling that she had as much of the centaurs cock inside of her as possible. Not long after she had bottomed out with eight inches of her cock inside her her co-worker, Kayla felt her balls tighten. A powerful climax then tore through the centaurs body as she began to pump Alyssa full of her semen, the flared tip of her cock ensuring that none of it spilled out. Alyssa was brought to the biggest orgasm of her life as she felt her co-worker fill her womb with cum, barley managing to remain standing.
When Kayla's orgasm had run it's course, Alyssa's stomach was bulging slightly from the sheer amount of cum inside her, significantly more than a horse could produce, let alone a human.
“That was amazing, I love the feeling of being completely filled with you cock Kayla, I wish I could stay like this forever...” Alyssa muttered, drunk off the aftershocks of sex.
“Yeah. This body feels so amazing, I'm not sure I even want to turn back after that” Kayla replied.
“Let's stay like this for a little while longer”
As Alyssa said that, something happened.
